I am the guy that was closest to the server :( and am actually a developer. I am getting this error, There are currently no logon servers available to service the logon request, when a machine on the domain is trying to be accessed from other machines from the network. Accessing other machines from this machine works as expected.

No. Really. This seems to be a network messup where your client doesn't see the domain controllers. Maybe there's something wrong with DNS or IP addressing, or anything else preventing proper communication between Client and DCs.

This happens on our Windows 7 laptops if not directly connected to the network after we install software onto them or do a Windows update. Is random but happens after updates often. Connecting the laptop to the physical LAN corrects the issue until the next update/software installation.
